  • ¼ teaspoon salt

  • 1 tablespoon canola oil
  • ½ cup yellow onion, diced

  • ½ teaspoon Worcestershire sauce

MUSHROOM SWISS SAUCE

  • ½ cup butter
  • 8 ounces mushrooms, sliced
  • ¼ cup beef broth
  • ¼ cup milk
  • ½ cup Swiss cheese, shredded
  • 1 pinch salt and pepper

SEASONED BUTTER

  • ¼ cup butter, melted
  • 1 teaspoon garlic salt
  • 2 teaspoons sesame seeds

SLIDERS

  • 1 package King's Hawaiian Rolls, 12 count
  • 12 slices Swiss cheese

Instructions

  • Preheat the oven to 350°F and spray a 9x13-inch baking dish with nonstick spray.

HAMBURGER

  • In a small bowl, mix together the seasoned salt, hamburger seasoning, salt, and pepper. Set aside.
  • Add the oil to a non-stick pan and add the onions and garlic. Cook about 1-2 minutes.
  • Add the ground beef to the pan. Break up the meat with a wooden spoon.
  • Add the Worcestershire sauce and sprinkle with the seasoning mixture.
  • Cook for about 8-10 minutes, or until no pink remains in the meat. Remove from heat and drain meat.

MUSHROOM SWISS SAUCE

  • In a medium saucepan over medium heat, melt butter.
  • Add mushrooms and cook for about 5-10 minutes. Add in beef broth and milk.
  • Reduce heat and slowly add cheese. Whisk constantly until the cheese is completely melted.
  • Add in cooked hamburger, and stir to combine.

SEASONED BUTTER

  • In a small bowl, mix together the melted butter, garlic salt, and sesame seeds. Set aside.

SLIDERS

  • Split your rolls in half, and place the bottom half in the prepared baking dish.
  • Add 6 slices of Swiss cheese, followed with the hamburger mixture, and then the second layer of 6 slices of Swiss cheese.
  • Place the top half of the buns on top and brush the tops of the rolls with the melted butter mixture.
  • Cover the dish with aluminum foil and bake for 20 minutes, or until the cheese is hot and bubbly.
  • Remove foil, and bake for an additional 5 minutes (or until the tops of the sliders turn a golden brown).
  • Remove from oven, slice and serve.
